Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitHub Desktop

  • There is no official Linux build; the application ships for Windows and macOS only, and the community fork at shiftkey/desktop that packages it for Linux is maintained separately and lags official releases, so a mixed-OS team cannot standardise on one client
  • Submodules are effectively unsupported: the app shows a submodule change as an opaque single line and gives you no way to initialise, update or navigate into it, so any repository using them needs the terminal anyway
  • History rewriting is limited to squashing and reordering local commits by drag and drop; interactive rebase, fixup chains, editing an old commit's contents and bisect are all absent, which is exactly the set of operations a beginner needs help with most
  • Pull request features only exist for GitHub remotes, so a team on GitLab or Bitbucket gets a plain Git client with an empty pull request pane and no review or checks view at all
  • Commit signing with a key that requires a passphrase generally fails, because the app cannot surface the pinentry prompt, and the resulting error message does not say that is the cause
  • GitHub staffs it lightly compared with its web and CI products, so long-standing feature requests and bugs sit open for years; if you file an issue you should plan around it rather than expect a fix

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets

Answered from the vendors’ own pages

GitHub Desktop: Is there a Linux version?

Not an official one. GitHub ships Windows and macOS builds only. A community fork, shiftkey/desktop, produces Linux packages, but it is maintained by volunteers and trails the official releases.

Nessus: What is the cheapest Nessus option?

Nessus Professional starts at $4,790 per year for a 1-year license. Multi-year commitments offer discounts, with 2-year licenses at $9,330.95 and 3-year licenses at $13,637.54.

Source
GitHub Desktop: Does it work with GitLab or Bitbucket?

For plain Git operations, yes: you can clone, commit, push and pull against any remote. The pull request, review and checks features only work against GitHub.com and GitHub Enterprise.

Nessus: What is the difference between Nessus Professional and Expert?

Nessus Expert costs $6,790 per year for a 1-year license (compared to $4,790 for Professional) and includes enhanced capabilities. Multi-year rates are available at discounted prices.

Source
GitHub Desktop: What does it cost?

Nothing. It is free and the source is published under the MIT licence, and it is separate from any GitHub plan you may or may not pay for.

Nessus: Does Nessus offer optional support or training?

Yes, Nessus offers add-on services: Advanced Support at $400/year provides 24x365 access to phone, email, community, and chat support. On-Demand Training costs $275/year for Fundamentals course access or $385/year for both Fundamentals and Advanced courses.

Source
GitHub Desktop: Will it handle submodules?

No. Submodule changes appear as an unreadable single-line diff and there are no controls for initialising or updating them. Repositories that use submodules need the command line.

GitHub Desktop: Do I still need to learn Git?

For everyday work, no. For recovery, yes. Anything beyond the curated set of operations, including interactive rebase and reflog recovery, happens in the terminal, so a team using it should have at least one person who knows Git properly.

GitHub Desktop: Does it work with GitHub Enterprise Server?

Yes. It signs in to GitHub Enterprise Server and GitHub Enterprise Cloud as well as GitHub.com, and it honours organisations that enforce SAML single sign-on.
